THEMIS-B: Electric Field Instrument, EFI, Electric Field Measurements. The L2 Product is a 3D Estimate of the perpnedicular Electric Field, Eperp, derived from the Spin Plane E-Field Measurements assuming E ⋅ B = 0, using relevant Flux-Gate Magnetometer, FGM, Data. This Data Product includes Spin-Averaged, and Fast Survey Field Data. The Spin-Averaged Data, EFS_DOT0, has approximately 3 s Time Resolution. Fast Survey, EFF_DOT0, Data has 0.125 s Time Resolution.

Measurements on the Axial booms, 5 and 6, may have large Errors due to their Proximity to the Spacecraft as the Axial Booms are much shorter than other Booms. The Spin Plane Booms for THEMIS were not deployed until January 14, 2008 at 1700 UT. Any EFI Measurements obtained prior to this Date and Time should not be used. See the THEMIS Website for more Information.
